So I've been listening to some music on these things, as well as watching the first season of Walking Dead (which I've been waiting on til I got my home theater back up).
I haven't played with positioning much yet. I ran a quick Audyssey calibration (one location only), and will let them settle in a bit before I start moving them around/running full Audyssey.
These speakers are very detailed. Vocals sound fantastic.
I briefly tried completely closing the back of the tweeter section, but found the diminished ambiance wasn't to my taste. As you can see in the pictures below, I do have some absorption up behind and to the side of the speakers.
I do find that with the open backs, some vocals sound like they have a slight echo--a little too open. Most sound good though. I may not have the sound panels positioned properly. At some point I'll stuff the acoustic fluff in there and see how that sounds to me.
With the Walking Dead, dialogue was very clear, and I was very pleased with the neutral sound. Nothing in my face, very natural sounding.
In the first picture below you can see my right surround & rear right speaker, as well as the SS8s and the HT2C, and one of my subs.
My whole setup:
- Denon 4311CI as both amp (to the rears & surrounds), and preamp (fronts, and center)
- Wyred4Sound MC3x500 (>500W into 8ohm, >1000W into 4ohm) for the fronts & center
- 2 Salk SS8s as fronts
- Salk HT2C as center
- 2 Rythmik F15HP subs
- 4 Mirage OMD-5s as surrounds/rears
